Short answer: the Teufel Rockster Cross for rock and jazz, the B&O A2 active for features. The Teufel has a pretty neutral frequency response and is more vocal and midrange-focused than the JBL Xtreme 4 thanks to a larger mid/bass driver. Its outdoor mode can sound somewhat harsh from a 4kHz peak and its bass is not as deep as the Xtreme 4, while the A2 offers customizable sound, a 22 hour battery and True360 sound but is not stereo.
Buy the Teufel Rockster Cross if you want one new; the B&O Beoplay A2 active is discontinued, so only look for it used.
If battery life is a priority, the B&O Beoplay A2 active is rated for 24 hours versus 16 hours for the Teufel Rockster Cross.
Water resistance is not close: the Teufel Rockster Cross is rated at IPX5 (water jets), well ahead of the B&O Beoplay A2 active at no water resistance.

Teufel Rockster Cross: $249.99 Amazon eBay
Newer model: the Teufel Rockster Cross 2, ranked higher, rated 4.2/5.
Pros: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver: better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release. Measured bass extension of 51Hz (-10dB).
Cons: Outdoor mode can sound somewhat harsh due to the 4kHz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.
